Can I build a NAS out of a desktop? [Request] (infosec.pub)

n00b question, sorry. If I had a desktop that could hold 4 HD and 2 SSD, could I turn it into a NAS? Could someone point me in the right direction if this makes sense?

No reason why not. May be a little power-hungry depending on the spec but if you already have it go for it. FreeNAS (now TrueNAS) is the usually suggested OS to run: https://www.truenas.com/freenas/

Since you have 4 HDD slots probably run 4 disks in a RAID 5 so think of how much space you need. RAID 5 is n-1 so if you have 4x 10TB drives you will be left with 30TB of space before formatting. You can calculate here: https://www.raid-calculator.com/

Then either mirror the SSDs for OS and caching or just use one. Depends on your budget really.

Nice, thanks so much for the info!

Power consumption is the main issue. If it's an old, power hungry desktop and you live somewhere with expensive electricity, it can be quite costly to run. If you have an energy efficient desktop or have cheap power then it will be fine. Just make sure it has a good quality power supply if it's going to run 24/7.

Maybe I'm dumb but looking at wikipedia I'm a bit confused. Seems like you can do this on almost any linux distro. What is the reason behind setting up a dedicated OS, cost of operation, stability, performance?

Not everybody has the knowledge to deal with Linux. A product line TrueNAS or Unraid has a friendly GUI that can be used by a non-technical user.
